Use Map Area Crime to view crime near a specific location / address or draw your own polygon of interest. Shows crime counts within the visible map area. Use Crime Dashboard to view crime by geographies like CPD District, CPD Beat, Ward and Community Area. Visualize how those polygons overlap. Includes interactive graphs like time of day & day of week. Both applications allow for filtering by date and crime types. Query results can be exported as a .csv file by using a button on the Nearby Crimes widget (Map Area Crime) or lower left on the Crime Incidents widget (Crime Dashboard). Be aware popup blockers may prevent downloading.

This dataset is ideal for analyzing crime trends, evaluating public safety measures, and studying the geographical distribution of incidents across Chicago in 2025.

Illinois Uniform Crime Reporting (IUCR) codes are four digit codes that law enforcement agencies use to classify criminal incidents when taking individual reports. These codes are also used to aggregate types of cases for statistical purposes. In Illinois, the Illinois State Police establish IUCR codes, but the agencies can add codes to suit their individual needs. The Chicago Police Department currently uses more than 400 IUCR codes to classify criminal offenses, divided into “Index” and “Non-Index” offenses. Index offenses are the offenses that are collected nation-wide by the Federal Bureaus of Investigation’s Uniform Crime Reports program to document crime trends over time (data released semi-annually), and include murder, criminal sexual assault, robbery, aggravated assault & battery, burglary, theft, motor vehicle theft, and arson. Non-index offenses are all other types of criminal incidents, including vandalism, weapons violations, public peace violations, etc.

The dataset is part of the Chicago Crimes records, selecting values of two years (2018 and 2019). The original data was downloaded from the Open Data portal of the City of Chicago, on May 29, 2020. The dataset was dowloaded from: https://data.cityofchicago.org/Public-Safety/Crimes-2001-to-present/ijzp-q8t2

This data is for Chicago crime data . which is give us details about crime happens over the year.

Introduction

Chicago is one of America's most iconic cities. It has a colorful history, which rich histories such. Recently, Chicago was also a setting for one of Netflix's popular series : Ozark. The story has it that Chicago is the center for drug distribution for the Navarro cartel.

So, how true is the series? A quick search on the internet reveals a recently released DEA report on the. The report shows that drug crime exists in Chicago, although they are distributed by the Cartel de Jalisco Nueva Generacion, the Sinaloa Cartel and the Guerros Unidos, to name a few.

Content

The government of the City of Chicago has provided a publicly available crime database accessible via Google BigQuery. I have downloaded a subset of the data with crime_type narcotics and year > 2015. The data contains records between 1 Jan 2016 UTC until 23 Jul 2020 UTC.

The dataset contains these columns : - case_number : ID of the record - date : Date of incident - iucr : Category of the crime, per Illinois Unified Crime Reporting (IUCR) code.

Inspiration

Some questions to get you started:

1. Is there a trend? Is the crime increasing? or decreasing?
2. Is there seasonality? Are dealers more like to be out and about in summer? Do they deal inside in winter?
3. Are some activities more like to happen at certain locations?
4. We tend to think that more deals happen at night, especially as people wind down, and the surroundings get dark. Does the data reflect that?
5. Are the incidents clustered to a certain district? Certain type of location?

Lastly, if you are : - a newly recruited analyst at the DEA / police, what would you recommend? - asked by el jefe del cartel (boss of the cartel) on how to expand operation / operate better, what would you say?

Happy wrangling!
